Yeah its hard to find a decent ka24 to swap and 50% of them fail the smog , due to high milage/ wore out engines. I have no doubt the sr20 will pass the smog with the cat in, and the emissions hooked back up it only has 30k on the clock..... its the visual test that will fail. My other option is to pay under the table to smog guy, but will still not protect me from the police. Socal cops are trained to check engine swap / mods and all this dumb bs. All this was brought up because thurs night I went to a weekly nissan meet , the police ended up coming thru the lot because it was a decent turn out about 15 cars or so ( they think car meet ups are street racing ) ...... Alot of the cars were slammed cars which is illegal to run a certain highth on a car here , 8 out of the 15 cars had to pop hoods and show carb legal stickers, 3 of the cars had engine swap which ended up getting towed and the other 5 guys had fix it tickets either being to low or not having a carb sticker on a certain mod. The police did not even hastle the out of state military guys , all they did was check id's and insurance and thats it.
